Someone else has already suggested using rsh and tar instead of rcp.
To complete the answer, though, it is possible (even easy) to rcp files
across different account names.  For instance, although I am
`chris@umdhost.umd.edu', I am `torek@ucbhost.berkeley.edu'; to copy
files between here and Berkeley, I could run

	[umd1] rcp torek@ucbhost.berkeley.edu:files dir
	[umd2] rcp files torek@ucbhost.berkeley.edu:dir
	[umd3] rlogin ucbhost.berkeley.edu -l torek
	[ucb1] rcp chris@umdhost.umd.edu:files dir
	[ucb2] rcp files chris@umdhost.umd.edu:files

Note that for this to work, chris@umdhost.umd.edu must be in the
.rhosts file of torek@ucbhost.berkeley.edu (for rcp run from umdhost),
and torek@ucbhost.berkeley.edu must be in the .rhosts file of
chris@umdhost.umd.edu (for rcp run from ucbhost).  (These entries tend
not to be there, for security reasons.  We will all run Kerberos soon
and use a different approach entirely anyway.)

Note also that 4.2BSD had a different syntax: rather than
`me@host:file', one had to write `host.me:file'.  The period was found
by scanning backwards from the colon, so that `host.long.name.me'
worked.  Of course, this meant that even where one had the same login
name on hosts in different domains, one had to type one's own
name---running like

	rcp ucbhost.berkeley.edu:file dir

would try to connect to `ucbhost.berkeley' as user `edu', rather
than `ucbhost.berkeley.edu' as user `$USER'.
